Hi,
I am not sure if anyone else is having this issue but the spiky wheel on the feeder stepper motor keeps coming lose. As a result of this, I get an uneven feed in plastic and the extruded plastic is uneven when printed. Does anyone know how to stop this? Is there a better part you can buy?
I have attached a photo of the part that keeps coming lose.
You may need to apply some locktite to the set screw. I have that same gear and it has been very reliable.
Try using a thread look (blue liquid, little red bottle), it’s like lock tight but not so permanent.
Do you have the set pin tightened and oriented over the flat surface?
I am planning a post with detailed descriptions and photos about getting the CTC printer up and running, I’ll make a note to include this in the post.

If the bore in your spiky wheel is too large, No matter what you do, the setscrew will come loose after a number of revolutions.
This is a relatively large problem.
Sorry I don’t have an easy solution other than attempting to replace your spiky wheel and using Lok-Tite sealant on the set
screw threads.
Actually, you might want to try painting the inside of the spiky wheel with epoxy glue and sanding it to fit properly, with
a bit of a push on fit.
That might just get you where you need to be!

Just a thought.
I have been having similar feeder issues. Extrusion is very blobby, and cuts out completely from time to time. Have you also been hearing an intermittent “ticking” noise coming from the feeder when it’s running?
I would be very interested in a setup guide for the CTC. I got one as a gift last week. It’s my first 3D printer, and I haven’t been able to get anything out of it since the first few prints.
Hi, Sorry for the delay but I have been away on holiday. Yes, I do hear a ticking noise coming from the feeder when it’s running. I just assumed it was the feeder wheel slipping as the little grub screw wasn’t tight.
